The Λ(1405) production in p+p collisions at 3.5 GeV and K−-induced reactions is discussed. The shift of the measured spectral function of the Λ(1405) in p+p reactions does not match either theoretical calculations for p+p reactions or experimental observation in previous K−-induced reactions. New experiments with stopped and in-flight K− are needed to study this initial state more in detail. The state of the art of the analysis is discussed.
